I drove it ten ignition cycles yesterday and about 80 miles of mixed highway and city. The numbers were solid. I drove it to work this morning and checked it once again. Still solid. I'm convinced its going to stay that way at this point. We had a pretty radical temp swing overnight and the numbers are still identical to yesterday.

I jus got tuned from gm stage 1 to trifecta e85. I have a k and n intake. I started throwing p0101 codes alot. Ive cleaned the maf. Any fix for this? Ive read the pages and gonna try to make sure maf is not touching metal intake.

5 seconds in HP tuners to bump this frequency from 10000 up to 13000 will make this issue dissapear forever.

If it were caused by grounding, I dont think increasing the fail freq would fix the problem....but it does. every time.
I'm having the same problem but can't figure out how to change it. I have hp, can you tell me where to go to raise that limit?

Is it fast
Thats intresting that you commented on the -16 to -17 stock. I never checked that before I changed. I know if you get a soft P0101 the engine will go into reduced power and hold the wastegate open. You also won't get a CEL unless it sees it twice in a row. Intresting.
Where did you find a mass air tweaker?
